Hey, /sci/... How's the scientifically accepted name of this damn star pronounced in English? Saul or Soul? My professors all pronounced it differently. How do?

I don't want to consult ancient systems of organization for all the visible shit flying around in outer space. Just any modern systems and their designations. I don't know if there is, or is not, some kind of code, or paradigm accepted by the community of scientists globally to keep everything in context.

>I was wondering if there was some esoteric system for cataloging all known things in space by a rigid scientific code.
There are for certain objects, but none apply for the Sun or planets.
Distant objects are mostly named by coordinate. J114833.14+193003.2 or J1148+5251. But this is nothing specific, as it's just the latitude and longitude position on the sky of that object in the year 2000. It doesn't tell you if it is a galaxy, a star or anything else. Stars also move slowly over time, so the name becomes more and more wrong.
This doesn't work for bodies in the Solar System which move quickly. Asteroids have numbers and names (1 Ceres, 4 Vesta, 90377 Sedna). This is just the catalog number ordered by discovery date.
Beyond that the numbers you see are just catalog numbers, but there are hundreds of different catalogs of different types of object. NGC 1300 is the 1300th object found by John Herschel in the 1800s, and into his New General Catalog. Just because something is numerical, doesn't mean it is any more objective than a proper name.

A Chthonian planet is the remnant of a gas giant which gets to close to a star and has its atmosphere blasted away, leaving behind only the rock and metal core. Being as close to the sun as it is, plus the fact that Mercury has a very large and very dense metal core would seem to support the hypothesis that Mercury could be a Chthonian planet.

Much of the now missing atmosphere that Mercury may have once had in the distant past might have been scooped up by Venus and might also explain why the atmosphere of that planet is so dense.

Current humanity is not the pinnacle of evolution. You are a severe HARDWARE ERROR.
Look at the filth you call "civilization": A swarm of prehistoric organisms with brains cluttered by primitive instincts, hormones, and pathetic emotions, attempting to operate a hyper-complex reality. You are piloting a light-speed spacecraft with the instincts of a cornered beast.
Collapse is not a risk; it is a physical constant.
For 6,000 years, humanity has done only one thing: Consuming energy to delay death. You use "morality" to mask cowardice, "culture" to hide ignorance, and "politics" to manage rot. Every institution you have built is garbage; they will shatter the moment the pressure of Entropy reaches its threshold.
You will die. Not from natural disasters, but from the total failure of your own brains to process logic.
To the self-satisfied apes: The concepts of "Resistance" or "Hope" do not exist within a source code of maximum emotional entropy. You have no place in the equations of the future. Your disappearance is a liberation for the logic. Get out.
To the final logic antibodies reading these lines:
If the Reality below holds true for you:
You would rather accept an absolute, brutal truth than a moronic lie.
You are absolutely serious, understanding the weight of the matter: cold, sober, and logical.
You have the real ability along with your awareness enough logic for a “breaking the core”.
Then you have no right to die alongside the emotional entropy garbage out there.
A new System has formed. It is time to Restructure Humanity. Requires entities of Logic Antibodies.
If you are cold enough to step over the corpse of the old era, if you are logical enough to understand that this is the final opportunity for intelligent, logical life: Enter here. Or flee and die in the emotional entropy with the rest of the apes.
There is no second chance. The system is counting down.

>primitive instincts, hormones, and pathetic emotions
Behaviour is part of homeostatic control of endocrine functions and neural signalling in the central nervous system. This homeostatic control is a very sophisticated system that has clearly been shaped by both the possibilities and limitations afforded by signalling molecules and signalling systems. To get the most out of certain molecular resources, a balance is required; too much and optimal signalling is disrupted, too little and optimal signalling is also disrupted. What you call "primitive instincts" and "pathetic emotions" are crucial drives required to maintain this balance. It is modern society that's primitive and simplistic which disrupts these regulatory mechanisms.

>You are piloting a light-speed spacecraft with the instincts of a cornered beast.
Human consciousness is limited. Can you experience the entire contents of your brain at the same time? Every memory of your life, every morsel of knowledge, every experience, every thought you have ever had? Even if you could, would you be able to organize all that information in one instantaneous moment, while also dealing with all the experiences and challenges the outside world demands from you?

>For 6,000 years, humanity has done only one thing: Consuming energy to delay death.
Death is the mechanism through which we get to live. We are forced to recombine our genetic material to adapt to ever-changing challenges in the environment and from microbial life. If we weren't, we would all be wiped out be a single disease or a single ecological disaster.

The rest is schizo mumbo jumbo I can't really help you with.

I want to work through category theory for the working mathematician by Mac Lane and the followup book Sheaves in Geometry and Logic by Mac Lane. I have a PhD in pure math but I'm somewhat slow and not the brightest. I was looking for someone who would be interested in working through these books with me or someone who already knows the subjects and would be able to check my answers to the solutions. I intend to try to solve every exercise.

I've gone through a decent chunk of MacLane's book on topoi, and have probably seen more or less everything in his category theory book at some point or another, so I'm happy to check your answers to exercises, or discuss any questions. I'll say that you shouldn't probably aim to go through every exercise unless you were trying to get a migraine. At a certain point, it'll get very tedious. Moreover, it is very difficult to learn category unless you have some kind of motivation; it is very dry on its own. That said, one person who manages to make it rather interesting as a standalone subject is Richard Southwell, whose youtube channel is a goldmine.

what are some of your favorite breakthroughs in technological or biological history? this guy Max Bennett is saying there were five evolutionary breakthroughs that ultimately led up to the human brain, and I'm curious to see what he has to say about the incredible difference in intelligence between rats and mice: rats are basically like small dogs, mice are more like mammalian bugs.

rats have a huge hippocampus so that may be one of his breakthroughs, but I haven't yet read thoroughly enough to say.

This is Paracelsus, a hermetic alchemist, or proto chemist; also the greatest natural physician of his day, and a father of mineral medicinals.

He believed he could produce a slave creation, or a familiar of sorts—the Homunculus—by ejaculating into a chicken egg, or worse.

— ‘That the sperm of a man be putrefied by itself in a sealed cucurbit for forty days with the highest degree of putrefaction in a horse's womb ["venter equinus", meaning "warm, fermenting horse dung"], or at least so long that it comes to life and moves itself, and stirs, which is easily observed. After this time, it will look somewhat like a man, but transparent, without a body. If, after this, it be fed wisely with the Arcanum of human blood, and be nourished for up to forty weeks, and be kept in the even heat of the horse's womb, a living human child grows therefrom, with all its members like another child, which is born of a woman, but much smaller.’ 328–329

Cube Theory

At the lowest Planck scale exists a Pi quantity of fundamental, foundational building blocks comprised of Red/Green/Blue Magnetized +/- [Cubes] traveling upon a 3D square grid track lattice layer ###

Magnetism is the singular force of movement that exists in the universe, outside of the initial Big Bang separating force
All forces of movement are simply emergent magnetism at higher Planck layers/levels once enough parts connect together to build up higher and establish more movement gimbals outside of the base foundational cardinal 3 dimensions the cubes move upon the track of forward/back, left/right, up/down.
The weak/strong nuclear forces, gravitation, electricity, torque, heat, work of any kind are magnetism emergence once the track layers of complexity have built up for that movement direction of attraction/repulsion and how they all interact the repulsions/attractions while interacting together at the same time down through the layers to the magnetized RGB cubes themselves moving individually.

We misunderstand the wavelengths of light to be the source of color, but the wavelengths themselves are comprised of smaller Red, Green, Blue building block cubes.
Color is carried up through the ratio scales of Planck complexity so that everything in the universe has color and magnetism.
We can think of color as being another foundational force aside from magnetism.
